There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

This file type includes high resolution graphics and schematics when applicable. Piezo ceramics are brittle, difficult to connect electrical leads to, and have no insulating protection to prevent ...

In the last 15 years, high-speed piezo electric actuators have become less expensive to manufacture. Consequently, they find themselves as a favorite design choice for a growing number of applications ...

Download this article in PDF format. Jacques and Pierre Curie, French physics, discovered the piezoelectric effect in 1880. When some solid material is mechanically compressed or stressed, the ...
